Waste-to-Energy Leachate Treatment Project in Yutian Coutry
1 Project Overview
The Yutian County Waste-to-Energy Leachate Treatment Project is a key environmental infrastructure project supporting the safe operation of a municipal solid waste incineration facility in Hebei Province, China.
The project focuses on the advanced treatment of high-strength landfill leachate generated from waste incineration processes. The system adopts a multi-stage deep treatment process to ensure stable compliance with strict environmental discharge standards and support long-term sustainable operation of the waste-to-energy plant.
The project introduces advanced softening and tubular ultrafiltration technology to improve membrane system stability and overall treatment efficiency, enabling full-capacity treatment and resource recovery of leachate.
